It was DS birthday yesterday. My Dsis text me wishing him a happy birthday. She lives 15 mins from me so not far. She doesn't work either so no daytime commitments. However she's made no effort to drop DS present off or even text me to say oh sorry ill drop his present off on this day. Its not the present but principle.
Dsis has form for this kind of stuff. For some reason when it comes to anyone's birthday or mothers/fathers day she tries to find someway to blow up or passes someone off in our family.
Aibu?
